Improving SC-FDMA Performance by Time Domain Equalization for UTRA LTE Uplink

Abstract

Single carrier frequency division multiple access (SC-FDMA) is used in the uplink of the next generation mobile communications standard Long Term Evolution (LTE). Based on a complete system simulation including channel coding and automatic repeat request, we compare a minimum-meansquare error block linear equalizer with an iterative equalization in time domain using a recurrent neural network structure. Based on the total throughput, iterative equalization in time domain shows a clear performance improvement for low signal-to-noise ratios (SNR). For a wide range SNRs turbo equalization leads to further throughput improvements.
